摘　　要：目的对不同生化检测系统检测结果的可比性进行评估。方法根据EP9-A2文件要求,对同一实验室两台生化分析仪系统中的天冬氨酸氨基转移酶(AST)、丙氨酸氨基转移酶(ALT)、碱性磷酸酶(ALP)、乳酸脱氢酶(LDH)及肌酸激酶(CK)进行测定,进行对比分析和预期偏倚估计。结果除ALP检测结果与比较方法的系统误差不可被接受外,其余项目的检测结果的系统误差均可接受。结论当使用不同检测系统检测同一项目时,需进行方法对比及预期偏倚估计,为确保临床检测结果可靠性提供科学依据。Objective To assess the comparability between different biochemical testing systems.Methods The research analyzed the results of serum enzyme in two biochemical analyzer and figured out the bias estimation by the document of EP9-A2 and explored the comparison of AST、ALT、ALP、LDH and CK in different detected systems.Results It is indicated that in the different biochemical analysis systems,the comparability of all the indexes could be accepted except for ALP.Conclusion In order to provide a scientific basis for clinic results,comparability test between the methods should be performed and figured out the bias estimation while use different detecting systems to monitor the same index.
